THOMAS STAPLETON, OF CINCINNATI, OHIO.

PERPETUALV CALENDAR.

SPECIFICATION forming part of Letters Patent No. 428,788, dated May 27,1890.

Application filed January '7, 1890. Serial No. 336,214. (No model.)

To all whom it may concern:

Be it known that I, THOMAS STAPLETON, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in PerpetualCalendars; and I do declare ,the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the gures of referencemarked thereon, which form a part of this specification.

This invention relates to calendars arranged after the perpetualplan-that is, after used one year they may be used again, and so onindefinitely until they become worn out. Those intended for use inoffices and other similar places are in many cases combined withinkstands or other articles found on the desk. It is this latter class,particularly, to which my calendar belongs, and I preferably combine itwith an inkstand, although it could be arranged on a frame by itself orcombined with some other suitable implementor fixture. For a morespecific description I refer to the accompanying drawings, in

which--v Figure 1 is' a front view, and Fig. 2 is a side view, of thedevice. Figs. 3, 4, 5, 6, and 7 illustrate modifications of the same.

9 is the inkstand proper, having one or two ink-receptacles within it.

10 is a more or less ornamental frame rising from the top of theinkstand. It may be of sheet metal or wire, Whatever is preferred orfound most suitable for the purpose.

11 11 are the principal parts of this upright structure and connectednear their upper ends by a cross-frame 12, which may be utilized forholding a tablet showing the year and being the only part of thecalendar which can be used only once, although it is hardly necessary toindicate the year, since this is a point about which mistakes do notfrequently 14, connected to them. This wire holds a number of tablets orchecks 15, bearing consecutively the numbers from 1 to 31, and are usedto indicate the date of the days. They are perforated and strung ontothe wire before its ends are connected. For appearance sake it isdesirable to have the foremost check in about a plane with the balanceof the frame. Ordinarily this could not well be accomplished, since bytheir weight the checks would slide forward and be far in advance of theother parts of the structure, were it not for the acute bend at 21 inthe endless piece of Wire 14 keeping them back.

In order to permit the checks 15 to pass back on wire 14, which isnecessary when the date is to be changed, they are provided with a slot16, running from the perforation by which they are held on wire 14 totheir outer edge, permitting them to pass easily, support-s 13 13sustaining wire 14 above and below. In order to have this operationclearly understood, it might be mentioned here that Supports 13 13 arethinner than the material of part 14, so that While the former easilyclear the slot in the checks this slot is not wide enough to let thechecks drop off of the thicker material of wire 14.

The months are indicated on tablets 17, which are perforated and strungon rings 18 1S, supported from a cross-piece 19, forming part of themain frame. vAt the expiration of a month they are changed by simplyturning the front one over to the rear, exposing the next lower one,which will show the correct month, having of course been originallyproperly arranged.

. IVhen the design is of such a character that it is not necessary tokeep the day-tablets back in a line with the main structure, they may besimply filed on a loose ring supported from a cross-piece 20, as shownin Figs. 3 and 4 of the drawings in a front and partial side View,respectively. In this case slot 16 may be dispensed with in the checks.

Another mode of securing the checks to their support 14 when this latteris not loose, as shown in Figs. 3 and 4, but sustained by braces 13 13,as illustrated in Figs. 1 and 2, is to construct part 14 out of a tubeslotted on IOO its outside, as shown in Figs. 5 and o', and to providethe cheeks l5 with a lug 22, as shown in Fig. 7.

llaving explained my invention, I claim as new- 1. In a perpetualcalendar, the arrangement and construction of the tablets or checksindicating the date of the days, and which consists in coniining them,movably and consecutively arranged, on a piece of wire, from which theyare suspended in such a manner as to permit their complete rotation onsaid wire, so they may appear in front again, all as shown anddescribed.

E2. In a perpetual calendar, the arrangement and construction of thetablets or checks indicating the date ot the days, and which consists inconfining them, movably and consecutively arranged, on an endless pieceof wire in such a manner as to permit their complete rotation on saidwire, so they may appear in front again, all as shown and explained.

3. .In a perpetual calendar, the arrangement and construction ot thetablets or checks indicating the date of the days, and which consists inconfining them, niovably and consecutively arranged,on an endless pieceof wire in such a manneras to permit their complete rotation on it, sothey may appear in front again, said wire having an acute bend in itslower portion, whereby said cheeks are retained in a certain positionthereon, all as fully shown and. explained.

4. In a perpetual calendar, the arrangement and construction of thetablets or checks showing the date of the days,and which consists inperforating and slotting them and strin ging them, con seeutivelyarranged, on an endless piece of wire, in combination with su pportssustaining the former in position, the slots in the checks clearing saidsupports when the date is changed, all as shown and described.

5. In a perpetual calendar, the arrangement and construction of thetablets or checks i11- dicating the date of the days, and which consistsin confining them, movably and consecutively arranged, on a piece ofwire in such a manner as to permit their complete rotation on said wire,so they may appear in front again, in combination with the tabletsshowing the names of the months, supported as shown, all as fully shownand illustrated.

(l. In aperpetual calendar, the arrangement and construction of thetablets or cheeks showing the date of the days, and which consists inconIinin them, movablyand consecutively arranged, on an endless piece ofwire in such a manner as to permit their complete rotation on said wire,so they may appear in front again, in combination with the tabletsshowingl the names ot the months, supported as shown, all as shown andexplained.

7. In a perpetual calendar, the arrangement and construction of thetablets or cheeks indicating the date of the days, and which consists inconfining them, movably and consecutively arranged, on an endless pieceof wire in such a manner as to permit their complete rotation on it, sothey may appear' in front again, said wire having an acute bend in itslower portion, whereby said checks are rctained in a certain position onit, in combination with the tablets showing the names ot' the months,supported as shown, all as illustrated and described.

8. In a perpetual calendar, the arrangement and construction of thetablets orcheeks showthe date of the days, and which consists inperforating and slotting them and stringing them, movably andconsecutively arranged, on an endless piece of wire, in combination withsupports sustaining the former in position, the slot in the checksclearing said supports when the date is changed, and a series of tabletsshowing the names of the months, suspended as shown, all as illustratedand explained.

0. In a perpetual calendar, the arrangement and construction ot thetablets or checks indieatingl the date of the days, and which consistsin perforating and slotting them at a point equally located in all andstrin gin g them, movably and consecutively arranged, on an endlesspiece of wire, in combination with supports sustaining the former, thematerial of the supports being thinner than the material of the ring, soas to permit the slot in the tablets running from the perforationstherein to their edge to clear said supports without permitting saidtablets to escape from their eoninement,in combination with a series oftablets showing the names of the months and strung on a cross-piece, thesupports sustaining the wire detaining the day-tablets and the partscarrying the month-tablets being incorporated and forming elements of astructure suitably arranged and combined to an inkstand, all as fullyshown and described.

In testimony whereof' I aflix my signature in presence ot two witnesses.
